Like the JCT, the ECI`s contractual conditions, the seventh edition and the FIDIC Red Book define preliminary amounts and contain provisions for their evaluation. However, neither form of contract is entirely clear as to the relationship between a provisional amount and the project programme. While there are extension provisions that can help a contractor in certain situations, they do not always apply. Preliminary total elements of a construction contract are elements of the project that cannot be accurately calculated in advance. The builder will include a “preliminary” amount in the contract based on their best estimate, and the final cost will be adjusted once the work is completed. What are the “defined” and “defined” provisional amounts? If you`re worried that preliminary cash can explode in value, ask your builder if anything can be done to pay the cost. Sometimes an engineer`s geotechnical report or a detailed investigation can provide enough additional information for the builder to determine the cost of the items in question. Lord Justice May described the preliminary amounts in Midland Expressway Limited v Carillion Construction Limited and Others  EWCA Civ. 936 (“Midland Expressway v Carillion”) as follows: The mechanism for adjusting the contract amount for profits and overheads to provisional amounts should be designed to take account of commercial intent.
Otherwise, especially when the provisional amounts represent a large part of the contract price, it can make a significant difference from the amount ultimately payable by the investor. In other words, if the price of a lump sum contract includes a provisional amount, the final amount to be paid by the investor is adjusted to reflect the actual cost of the provisional total labour. Where undefined interim amounts are included in the contractor`s price, the employer should consider giving due consideration to the risk of compensation being exceeded in its risk register. In particular, a contractor may claim that work falls below the provisional amount (and is therefore subject to adjustment), while the principal or superintendent may consider that the work should have been approved under the contractor`s fixed price. The new Measurement Rules (NRM) published by the Royal Institute of Chartered Surveyors (RICS) suggest that work relating to a defined provisional sum should describe the following: Provisional amounts defined are when sufficient detail has been provided to the contractor to include in its price and programme. This detail could include a certain level of design, an understanding of the construction phase, the likely quantity, and any known specific limitations. However, if all this is provided, it leads to the question: Why give a preliminary sum, instead of just evaluating the article? The reason may be that, although there is enough information for the entrepreneur to set a price, there may be a high degree of uncertainty. For example, the finished product cannot be selected, the conditions are too unknown, or the final quantity may differ. The main costs are very similar to the preliminary sums and often work in the same way.
A main cost item is a provision for a specific delivery item for which the final selection of the item has not yet been made at the time of the conclusion of the contract. At Ramsay Builders, we pride ourselves on staying ahead of the market with the latest trends, techniques and materials and ensuring the best construction experience for our customers. For these reasons, interim amounts should only be used as a last resort, they should not be an easy fallback for consultants when projects are incomplete or information is difficult to obtain. The risks are so great that the engineering and construction contract neC3 (NEC3) does not contain any provisional amount. A cost factor is defined as “an item that has not yet been selected at the time of entering into a domestic construction contract or whose value is not known, and whose customer must take due account of delivery and delivery costs in the contract”. Some contracts provide that a percentage must be applied to the actual cost of performing the preliminary sum work or delivering the main cost item. Examples include AS 4000 (Section 3) and AS 2124 (Section 11). Is it necessary to have the list and breakdown of prices for provisional total items under FIDIC contracts? Disputes regarding provisional amounts sometimes arise when the description of the provisional amount is ambiguous. For more information, see Preliminary sum not defined.
A common example is tapware. If your builder hasn`t specified a specific make, model, and style of faucets, or if it`s impossible to get a fixed price for what you want, your builder will likely assign some value to the faucets instead of specifying the exact costs. You can then select faucets at this value from the agreed suppliers. 1. Is the provisional sum equal to the variation if SO expands it further?
